APPARATUS FOR DRAWING WIRE.

SPECIFICATION forming part of Letters Patent No. 331,680, dated December1, 1885.

(No model.) 1

T0 aZZ whom it may concern:

Be it known that I, SAMUEL HENRY BYRNE, a subject of the Queen of GreatBritain, residing at Brighouse, in the county of York, England,wire-manufacturer, have invented certain new and useful Improvements inApparatus for \Vire-Drawing, of which the following is a specification.

This invention has for its object improvements in apparatus forwire-drawing.

My invention is especially applicable when drawing wire at one operationthrough a series of rotating dies, as is described in the specificationof a former patent granted to me June 9, 1885, No. 3l9,556 but it isalso applicable when drawing wire in other ways.

The invention relates to the dies through which the wire is drawn.

The dies which I employ are of the mineral known as bolus or pea bort.The eye is drilled in the mineral in the same way as diamonds and otherjewels have heretofore been drilled for wire-drawing, and the stone isin like manner set firmly in a metallic setting. The usual way is toinsert the stone into a hole in a piece of sheet-brass, and there retainit by the aid of tin or fusible metal.

In order that my said invention may be most fully understood and readilycarried into effect, I will proceed to describe the drawings hereuntoannexed.

In the drawings, Figure l isaside elevation, and Fig. 2 is a plan,indicating the arrangements of the machine which I employ. Figs. 3 and 4show separately, to a larger scale, one of the die-holders and partsimmediately in connection therewith; and Figs. 5 and 6 show the diewhich is received into the said holder.-

The frame a carries the bearings for the axis of the pulleys b, N, b,b", and b and by suitable driving-gears these axes can be so driven asto give any desired surface-speed to the periphery of the pulleys. -c isa drum, also carried by the frame and capable of turning freely. Upon itis placed the wire as it is brought to the machine, and the wire unwindsfrom this drum as it is drawn forward through the dies. (1 is anotherdrum on which the wire is wound as it comes from the dies. The axis ofthis drum is driven in order that the drum may wind up the wire as it isdelivered to it. (2, c c c and e are brackets on the frame carrying thedies.

The dies consistof bolus or pea bort perforated and set concentricallyin a metal disk, and this is inserted into a holder which is pro videdwith a hollow axis through which the wire passes. The holder in eachcase has spur-teeth upon its periphery, which engage with correspondingteeth upon a pinion on an axis, j, which is slowly rotated in order toimpart a continuous rotary motion to the dies while the machine is inaction. In all these features, excepting the use of bolus or pea hurt inthe die, the machine resembles that for which a patent has already beengranted to me, No. 319,556.

The wire passes into the machine from the drum 0, first through the dieon the bracket 0, thence once around the pulley b, next through the dieat 6 and to the pulley at If, and so on until it arrives at thereceiving-drum d. The surface-speeds of the pulleys b, If", 1), b and bare carefully adjusted to accord with the extensions of the wireresulting from its passage throughthe dies.

f, f f f, and are nozzle-tubes on the pipe f, and stop-cocks areprovided in connection with them. The nozzles, of which the openings maybe an eighth of an inch in diameter, are so directed that the streams ofliquid issuing from them impinge in each case at the eye of the die.Theliquid which I have found most suitable for the lubrication of thedies or for application to the dies in this man nor is prepared byboiling one part of softsoap with thirty parts of water until perfectsolution is obtained.

Beneath the pulleys b, b b 1), and b a trough 0r troughs are provided,in which the said pulleys are immersed nearly up to their axes. Thistrough, to avoid confusion, is not represented in the drawings. Itcatches the liquid issuing from the jets after ithas inipinged upon thedies. Thisliquid is returned to the cistern in any convenient manner.

Bolus or pea bort is a form of carbon found in the beds which also yielddiamonds. The shape it takes is that of pea-like balls, either clear ormore or less colored. It will not cleave like the diamond in parallelplanes, but its structure is radial. It is both tougher and harder thandiamond.

In the use ofdiamonds in the machine above described, the loss bybreakage is found to be very serious, not only on account of the cost ofthe gem, but also and mainly on account of the delay in working, towhich such breakages give rise.

When the eye is formed in bolus or pea bort, the stone rarely breaks,and such dies are very durable.

My invention is applicable not only to the drawing of wire of iron andsteel, but also to drawing wire of copper or brass, and specially finewire. Wire of any metal from which wire is usually made, and wire ofvarious sizes, may be produced in accordance with my invention.

My invention also, although especially advantageous when drawing at oneoperation through several rotating dies, is nevertheless useful inwire-drawing by themore usual and simpler methods.

the wire is drawn continuously at one operation.
